Speaking as an engineer who's worked in product liability stuff in the past, and currently works in product R&D... of course there was FEA done, and hopefully a bunch of other testing. But there's a lot of conventionally designed stuff that has gone through FEA and testing only to fail in ways that the original designers didn't expect later on, and plastics get to adding a whooooooole bunch of reliance on your supply chain being spot on, all the time. I'm sure it was conceived with the best of intentions, but man, no.

It might have passed all the tests but I maintain it's a horrible idea until we have samples that have survived 8 years of slushy and salty roads. And 100 degree temperature swings.

I went to CMM programming training with a guy who has to measure plastics. Trying to hold a tolerance with plastic other stuff like virgin peak seemed like a losing battle, especially with sinks and all the other molding problems plastic is prone to. Isn't plastic covering metal one of the reasons chrome clad wheels on Dodges rot even faster than straight steelies?

The major advantage to composite manifolds is you can rush out rapid updated manifolds to solve the issue.

And then the fuckers lie to you - they up the amount of regrind or reduce the amount of reinforcement and dare you to catch them. Or they get undercut by another supplier, purchasing goes with them, and then after the design for the new supplier gets validated, after a year's worth of parts they start upping the amount of regrind or reducing the amount of reinforcement and daring you to catch them.

It's still so many hundreds of times simpler to live on a polluted hellscape Earth than a sterile space station or moon base. Basically, the only way that living off-world is better, would be if the environment was so far gone that you couldn't breath the air.

Humans haven't even figured out what a balanced diet is, opinion changes every ten years about what will and what won't kill us. And the rich folks are talking about colonizing mars? That Matt Damon movie was the absolute best case scenario, it's far more likely we spend a hundred years sending people to a horrible death before we start to figure things out.

Rich people have to believe in some dumb poo poo to justify the damage they're doing to people/the planet. Some believe humans can escsape once the planet is a flaming husk, others believe we're living in a simulation so the people they refuse to pay a living wage aren't actually people. In conclusion, eat the rich.

Headlights falling out? It's got to be a Porsche. Macan would be my guess I guess they never bothered to redesign the headlamp mounting. They kinda just slide in and have a latching arm that you manually turn with a long specialized key, can be a bit of a bitch to latch correctly, and apparently made it very easy to steal the lights from various generations of Cayenne, whatever the big SUV is spelled.

# ? May 31, 2018 20:48 |

They are! Due to the relative ease and speed of stealing them due to not necessitating opening the hood, high value / quality, and apparently being a decent grow light for your other enterprise.

# ? May 31, 2018 20:53 |

Also, the fact that they're stolen so much while being easy to install means there's always a market of people who want cheap don't-care-where-you-got-it replacements, which encourages more people to steal them, which increases the demand, in a glorious self-perpetuating cycle.

Pressure washer slowed down, sparked and stopped, 240v karcher. Step one, take it apart and giggle at how little the actually is in here. Then notice the carbon and copper chips... Looks like the commutator poo poo the bed, brushes lasted about 5 seconds after that. It would technically still run if I put new brushes in, for about 5 seconds before it ate them too. This cost me £45 I think, 2 years ago. New motor is about £45, do the math.
